What do I care about Biology?
Biology is a broad field
• Multidisciplinary• Chemical machines
inside our cells• Ecosystems and
Global Climate Change.
Career Genetics
Human Genome
• DNA sequences
• Deoxyribonucleic Acid, in native form is a double stranded helix
Model of DNA
Career Molecular Biology
Stem Cell Research
• President Bush appears at his ranch in Crawford, Texas, after announcing he supports funding for limited stem cell research, Thursday, Aug. 9, 2001. Bush decided on a compromise and will limit federal funding for embryonic stem cell research. The decision had been one of the toughest for Bush since he
took office.

AstrobiologyIn what may be their most significant discovery yet, Mars scientists say high-resolution pictures from MGS showing layers of sedimentary rock paint a portrait of an ancient Mars that long ago may have featured numerous lakes and shallow seas. This was hinted at by old Viking images, but the new MGS images are pretty compelling.

Descriptions and Mechanisms
What is Life?
Ingestion, metabolism and excretion
Departure from thermodynamic equilibrium
Nucleic acids, proteins and other macromolecules
Reproduction, mutation and reproduction of it's mutations
(Carl Sagan (1934-1996) Scientific American 10/94, p94)
Creating Life in a Computer
Artificial Life Researchers... "define life not by it's substance but by its
organization, which can include the patterns of information in a computer. They believe
that life in all it's forms has a mechanism for processing energy and information that
emerge from some fundamental order in the universe, a new natural law that shapes those
forms out of chaos." Byte 1/95 p45
